Whirlpool & KitchenAid Dishwasher Thermal Fuse Parts — Models & Compatibility

Your Whirlpool or KitchenAid dishwasher won't start, and you've traced the problem to the thermal fuse — a small safety component that opens when temperatures exceed safe limits. This hub covers the W10258275 bi-metal thermal fuse kit that protects your dishwasher's control circuit from overheating. Whether you're working on a Whirlpool GU2275XTVY3, a KitchenAid KUDA03CTBS series, or any of the dozens of compatible models, you'll find the compatibility info you need here.

Is This the Right Part for Your Model?

First things first: grab your dishwasher's model number. On most Whirlpool and KitchenAid dishwashers, you'll find it on a label along the top edge of the door opening or on the side of the door itself. Match your model number against the compatibility list below — this fuse kit fits GU, DU, and KUDA series dishwashers manufactured between the mid-2000s and 2010s. If your dishwasher won't start and shows no signs of life, the thermal fuse is often the culprit.

About This Replacement Part

The thermal fuse opens when the temperature gets too high, protecting the circuit from overload. It's a one-time safety device — once it blows, you can't reset it. Common symptoms include a dishwasher that won't start or won't drain, even though you can hear the door latch click. One technician described the diagnostic process: "Removed the screws to access the controls. Used my volt meter to check circuits. Found an open circuit on the thermal fuse." That's exactly how you'll diagnose this — with a multimeter checking for continuity. No continuity? The fuse has done its job and needs replacement.

What You'll Need for Installation

This is an easy repair that takes less than 15 minutes. You'll need basic screwdrivers to access the control panel and a multimeter to verify the old fuse is blown before ordering. The W10258275 kit includes the fuse and necessary connectors. Most techs recommend checking what caused the overheat in the first place — a stuck relay or shorted component — so you don't immediately blow the new fuse.

Installation Overview

The repair difficulty is rated easy. You'll disconnect power, remove the lower access panel or control panel (depending on your model), locate the thermal fuse near the control board, disconnect the wire terminals, and install the new fuse. The trickiest part is accessing the control area — some models require removing the entire door panel, while others give you access from below. Check a model-specific video before you start so you know which screws to remove.
